Anyware AZA-230W White USB + PS/2 Slim Foldable Waterproof Dustproof Keyboard - Retail

Flexible and waterproof while being very usable! Very good for the occasional LAN party or backup keyboard.

Not for everyday use.

it is pretty hard to type on, but you do get used to it.

Water-proof, all the buttons work, highly-flexible, and the keys are low (like a laptop key-board).

Shift key is tricky, and when it gets cold, it feels like there is a bubble between the front and back membrane, and the keys are further apart than a regular keyboard.
